It replaces GPT-5.6 Terra and sits between GPT-6 Luna and the higher-capability GPT-6.1 Sol and GPT-6 Astra. The API id is gpt-6.1-terra, and Plus, Pro, Enterprise and Edu users get it in ChatGPT Work and Codex. Computerworld, quoting OpenAI, reports $1 per million input tokens, $5 per million output tokens and $0.05 for cached input. AWS's Bedrock model card shows the same rates for global routing, a 1,050,000-token context window and 128,000 maximum output tokens. Bedrock charges more above 272,000 input tokens: $2 for input and $7.50 for output.\n\nOpenAI's benchmark figures, as Computerworld reports them, were run at maximum effort. On Agents' Last Exam, Terra scored 60.0% at $1.01 per task, against 50.7% at $3.58 for GPT-5.6 Terra, 58.6% at $2.00 for GPT-6.1 Sol and 59.3% at $7.24 for GPT-6 Astra. Claude Opus 5.5 scored 63.2% at $8.82. On OSWorld 2.1, Terra scored 74.2% at $1.19 per task, and Claude Sonnet 5.5 led at 83.9% and $5.74. OpenAI's system card treats Terra as Critical in cybersecurity and High in biological and chemical capability.","whyItMatters":"OpenAI says the list price is at least 50% below GPT-6.1 Sol's and GPT-5.6 Terra's, so a high-volume job on either could cost much less. The task-level numbers matter more. OpenAI's own test has Terra at $1.01 per task against $3.58 for GPT-5.6 Terra. Those figures are OpenAI-reported, at maximum effort, and Opus 5.5 still scored higher on that test at $8.82.\n\nToken price, score and cost per task are three different measures, and review time can erase a saving. Put one recurring job through Terra and compare finished work, including the minutes a person spends checking it.","issuer":"OpenAI","glance":"OpenAI launched GPT-6.1 Terra October 26 at $1 in and $5 out per million tokens, replacing GPT-5.6 Terra.","keyFact":"$1 in, $5 out per 1M tokens","action":"Run one recurring task on GPT-6.1 Terra and compare cost per finished task.","attachments":[{"title":"Addendum to GPT-6 Astra System Card: GPT-6.1 Terra","url":"https://deploymentsafety.openai.com/gpt-6-1-terra","description":"OpenAI's safety documentation for Terra: the Critical cybersecurity and High biological and chemical classifications, the safeguards stack shared with Sol and Astra, and the safety and hallucination evaluations.","source":{"title":"Addendum to GPT-6 Astra System Card: GPT-6.1 Terra","url":"https://deploymentsafety.openai.com/gpt-6-1-terra","date":"2026-10-26"}},{"title":"Amazon Bedrock model card for OpenAI GPT-6.1 Terra","url":"https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-openai-gpt-6-1-terra.html","description":"AWS's launch date, 1,050,000-token context window, 128,000 output limit, regional price tiers and the above-272,000-token long-context rates.","source":{"title":"Amazon Bedrock model card for OpenAI GPT-6.1 Terra","url":"https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-openai-gpt-6-1-terra.html","date":"2026-10-26"}},{"title":"OpenAI bets on AI economics with lower-cost GPT-6.1 Terra","url":"https://www.computerworld.com/article/4241023","description":"Computerworld's report quoting OpenAI's price list and the maximum-effort Agents' Last Exam, OSWorld 2.1 and MMMU-Pro results with cost per task, plus an analyst's caution about review costs.","source":{"title":"OpenAI bets on AI economics with lower-cost GPT-6.1 Terra","url":"https://www.computerworld.com/article/4241023","date":"2026-10-27"}}],"evidenceNote":"OpenAI's announcement page returned an access error to automated retrieval, and no official chart image URL could be verified.
